NORTH AMERICAN COLEOPTERA. 21") 



In the collection of Mr. Schwarz there is a female specimen of a spe- 

 cies very closely allied to the preceding but differing in its paler and 

 somewhat more robust antennae,. and a head a little more broadly oval. 

 It is labeled Schwarzi Fauvel. I do not feel at liberty with such insuf- 

 ficient material to give it a name, as I have used the same designation for 

 a more imposing species. 



P. virilis n. sp. — Form of -nigritiUini, somewhat more robust,, rufo-pieeou.s, 

 shining; legs testaceous, the inid(lh> and posterior tiliia; somewiiat darker; antenna; 

 as long as the head and thorax, brown, joints 5-10 gradually shorter and broader; 

 head oval, darker, a few coarse punctures at the sides : thorax a little w ider than 

 the liead, longer than wide, not narrowed in front: sides scarcely sinuate, dorsal 

 punctures five, not large; elytra a little wider than the thorax, slightlv wider 

 behind, not longer than wide conjointly; surface shining, coarsely and sparsely 

 punctured, scarcely at all pubescent; abdomen darker than the elytra, punctua- 

 tion finer but very sparse, pubescence very s])arse: beneath as above. Length 

 .18 inch ; 4.5 mm. 



Male. — Tarsi slender; last ventral with a large and broad triangular einargina- 

 tirin fimbriate within with rather long stiff' hairs. 



Female. — Tarsi slender; last ventral entire. 



In its general appearance this species does not differ notably from many 

 of the forms of microphthalmus, mgritulus or crassulii.s. The sexual 

 characters of the male mark it as very distinct. The emargination of 

 the last ventral in that sex is greater proportionately than in any other 

 species known to me, and occupies at least one-third of the superfices of 

 the segment. 



Two specimens, Vancouver. 



P. puiictatellns n. sp. — Form slender, elongate, piceous, moderately shin- 

 ing; legs testaceous; antennae piceous, shorter than the head and thorax, joints 

 5-10 not longer than wide, the outer ones broader than long; head oval, slightly 

 oblong, hind angles not punctulate ; thorax very little wider than the head, longer 

 than wide, slightly narrower in front, dorsal punctures five, equidistant, and 

 rather deeply impressed ; elytra wider than the thorax, slightly broader behind, 

 longer than wide conjointly; surface rather shining, very sparsely pubescent^ 

 punctures coarse, regularly but not closely placed ; abdomen above with sparser 

 and less coarse punctures than the elytra; beneath sparsely punctate. Length 

 .24 inch ; 6 mm. 



Male. — Anterior tarsi slender, filiform : last ventral segment with a broad pel- 

 lucid border, and with a triangular notch in the border and in the corneous portion 

 of the segment also. 



Female. — Tarsi filiform; last ventral entire. 



This species resembles some of the larger forms of nigritidus.^ but 

 the elytra are more coarsely punctured. In the latter respect it resem- 

 bles hidentatus. The sexual characters of the male are the only positive 

 means for distinguishing the species. 



Occurs in the Hudson's Bay region, and at Lake Tahoe.
